miss you big boy

you might be interested to know that Working Trials is based on a Competitive Civilian form of Polive Dog Handling, hence the names of the stakes - PD being Patrol Dog...

I simply think it would be extremely difficult to train these methods and get the dog motivated enough without the use of positive reward.

The Police sometimes come and compete, they did more so in the past I understand.
